What to Do About Excessive Vegetative Growth in Mango Trees in Winter? Here Come the Latest Solutions

Mango trees are highly prone to excessive vegetative growth in winter, which consumes the tree's nutrients, weakens tree vigor, directly affects the quality of winter dormancy of mango trees, prevents them from overwintering normally, and also poses a threat to the yield of the coming year. So what should be done about excessive vegetative growth in mango trees in winter? Follow the editor to take a look.

1. Controlling shoots

Traditional methods for controlling excessive branch growth mostly use girdling, shoot killing and root pruning, and these measures cause relatively great damage to tree vigor and will greatly shorten the lifespan of the tree. Practice has proved that the method of applying a new type of agent to the girdling cut is extremely effective for preventing rampant branch growth. The method is: in October to November, use a knife to girdle the smooth part of the mango tree trunk down to the xylem, then use a protective agent to smear back and forth over the girdling cut, so that the agent enters the gaps. After the agent enters the tree, it can disinfect and activate the anions in the tree, causing it to transform from vegetative growth to reproductive growth. In this way, it can control excessive branch growth, improve dormancy quality, and enable the tree to bloom and set fruit more in the coming year.

2. Pruning

In winter, prune off diseased and pest-infested branches and leaves, weak branches, shaded branches and drooping branches on the fruit tree, cut back part of the fruiting branches, and prune the dense buds on fruiting branches. At the same time, burn the pruned branches in a centralized manner. If the wounds after pruning are not sealed in time, they will crack, be threatened by contamination and pests and diseases, and cause tree vigor to decline. Therefore, a healing agent can be applied to the pruning cuts to form a water-impermeable, tough layer that adheres closely to the wood, protecting the wound and the growth of wound tissue.

3. Fertilizing

After mango fruit harvest, attention should be paid to base fertilizer and light. The base fertilizer should mainly be decomposed farmyard manure, reasonably combined with nitrogen-phosphorus compound fertilizer and applied in furrows, with soil covering after fertilization. Avoid applying large amounts of nitrogen fertilizer in the base fertilizer, so as not to cause a second round of excessive growth. Farmyard manure takes effect slowly and needs a relatively long time for transformation before being absorbed by the root system, so it will not cause excessive growth of the fruit tree after fertilization.

4. Cleaning the orchard

In winter, clean the orchard by removing weeds in the orchard, building terraces, deeply plowing the orchard to improve the soil, covering the tree disk with grass, whitewashing the tree trunks, and using the winter slack time to accumulate organic fertilizer. Before closing the orchard in winter and before bud break in spring, spray fungicides and insecticides throughout the orchard, whitewash the trunks to protect against cold, and through spraying, eliminate pests and diseases that overwinter on mango trees, with excellent effects such as suffocating sterilization and heat preservation and antifreeze.
